PROBLEM TO BE SOLVED: To provide a sheet-like oil adsorbing material of a slight oil leakage amount.SOLUTION: An oil adsorbing material is characterized by linearly and adjacently arranging each of mat-shape oil adsorbing materials while lining the same in a direction where leakage quantity of oil is little and coupling the adjacent mat-shape oil adsorbing materials by couplers respectively. The oil adsorbing material is constituted by applying a mark to a hanging position of the mat-shape oil adsorbing material where an oil leakage amount lessens when hanging. |
